Design and Implementation of Model-Predictive Control With Friction Compensation on an Omnidirectional Mobile Robot
(IEEE, 2013)
This paper presents and discusses the implementation results of a model-predictive control (MPC) scheme with friction compensation applied to trajectory following of an omnidirectional three-wheeled robot. A cascade structure ...
Intruder in a two-dimensional granular system: Effects of dynamic and static basal friction on stick-slip and clogging dynamics
(American Physical Society, 2020-01-31)
We present simulation results for an intruder pulled through a two-dimensional granular system by a spring using a model designed to mimic the experiments described by Kozlowski et al. [Phys. Rev. E 100, 032905 ...
Computational modeling of 2D frictional contact problems based on the use of coupling finite elements and combined contact/friction damage constitutive model
(2022-02-01)
This work proposes a new approach to describe 2D frictional contact problems based on the use of coupling finite elements (CFEs) and a combined contact/friction damage constitutive model. This technique is able to establish ...

A simple alternative to the phone book friction demonstration
(2018)
In this paper we describe a simple alternative to the telephone book friction experiment, a classic demonstration where a small force (generated for example by the bending of the outer pages) is amplified by the large ...

Determinação experimental de Coeficientes de Atrito de diferentes partículas para aplicação na modelagem de escoamentos densos
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2022-08-31)
Systems involving particles are very common in many engineering applications. The interaction between these particles and of them with the equipment surfaces can strongly affect their dis-tribution, which will often influence ...
Coeficiente de atrito estático do par aço AISI H13 temperado e revenido e recobrimento de cromo duro: ensaios em plano inclinado
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Mecânica e de Materiais, 2011-09-29)
In this work was studied the influence of roughness parameters and mechanical properties of the steel AISI H13 in the coefficient of static friction tested in the inclined plane method. The counterbody used was a coating ...
Motion-induced radiation due to an atom in the presence of a graphene plane
(MDPI AG, 2021-05)
We study the motion-induced radiation due to the non-relativistic motion of an atom, coupled to the vacuum electromagnetic field by an electric dipole term, in the presence of a static graphene plate. After computing the ...
